Independent Trolley Rotomolding machine

Independent Trolley rotomolding machine is a multi-station universal rotomolding equipment. Its each arm's moving technology cycle(rotational speed, heating temperature and time, cooling, etc). is independent of the orher arms. It  adapte to the different materials, and can produce different products and meet the technical requirements, make the process cycle of  products flexible. It is also one of the most efficient rotational molding equipments. It can be divided into 3,4,5 arms and 4,5,6 position optional forms, coling chamber have 1-2.

Working Cycle

Available with up to 6 stations for maximum flexibility:
1   Cooking and moulding the article;
2   Intermediate phase waiting for cooling;
3   Mould cooling station;
4   Waiting station for mould opening;
5   Material loading;
6   Waiting or pre-moulding station for second layer or sandwich.
Depending on the customer requirements, the work stations can be arranged in a different way.

Main Features

1   PLC controls to manage the machine;
2   Long life gear in the head of the arms ;

Machine Parts

The equipment is designed in conjunction with the recirculation system of high capacity air (equipped with starting and speed control by frequency inverter) and the heating system with high efficiency in each cycle.

Electrical Part:

 It is equipped with a General Panel where are installed and interconnected all programmable and eletromechanical components such as PLC (Programmable Logic Controller), computer, contactors, motors breakers, power supplies, transformer, VFDs (variable frequency drives), push buttons, selector switches and light/sound alarms. This panel is mainly used to set the recipe parameters for the production.

Control Parts:

The PLC is loaded with a software management control system, which gathers information from multiple sensors such as temperature and pressure, installed in various parts of the machine, doing all the interlock and control functions of machine operation and providing a specific and concise input to the controller of the gas burner.

Arms:

The Carousel machine model can be equipped with Straight arm or optional Offset arm "C", both built with a reinforced structure and heat treated for steel stress release.
